[PATCH v3] trace-cmd: Add dependencies to BUILDING section in README

[Victor Cora Colombo <victorcora98@gmail.com>]

KernelShark has instructions in its README on how to get necessary
dependencies to build it. trace-cmd could follow this example and
also add more information on how to build it.

This patch adds instructions to README on how to get necessary libraries
and dependencies to build trace-cmd.

 BUILDING:
 
+In order to install build dependencies on Debian / Ubuntu do the following:
+    sudo apt-get install build-essential git pkg-config -y
+    sudo apt-get install libtracefs-dev libtraceevent-dev -y
+
+In order to install build dependencies on Fedora, as root do the following:
+    dnf install gcc make git pkg-config -y
+    dnf install libtracefs-devel libtraceevent-devel -y
+
+In case your distribution does not have the required libtracefs and
+libtraceevent libraries, build and install them manually:
+
+    git clone https://git.kernel.org/pub/scm/libs/libtrace/libtraceevent.git/
+    cd libtraceevent
+    make
+    sudo make install
+
+    git clone https://git.kernel.org/pub/scm/libs/libtrace/libtracefs.git/
+    cd libtracefs
+    make
+    sudo make install
+
 To make trace-cmd
