Update the way of checking resource table name with prefix substring search
instead of complete string search.

In general, Qualcomm DSP binary is prepared by combining different ELFs'.
Hence, section header name (e.g. .resource_table), appended with ELF name
to differentiate with same section(e.g. resource_table.ac_bin_process) of
different ELFs'.

Example readelf output of DSP binary:
    [60] .start.ac_bin_process PROGBITS
    [61] .resource_table.ac_bin_process PROGBITS
    [62] .comment.ac_bin_process PROGBITS
